Abstract

Improvements in positive displacement pumps for the simultaneous simultaneous discharge of predetermined unequal quantities of at least two viscous liquids, characterized in that each pump is provided with a transmission device arranged to produce the simultaneous reciprocating movement of at least two pistons of pumping, each pumping piston sliding in a respective pumping cylinder, each pumping cylinder connecting to a respective valve which selectively opens into a respective inlet or outlet mouth of liquid so, in practice, the reciprocating movement of the pumping pistons within the pumping cylinders produces simultaneous pumping of predetermined unequal amounts of liquids from the inlet ports to the outlet ports.
